NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a
       running MySQL database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       •   /etc/pcpdbi.conf

       •   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start
       of pmdamysql.pl, namely:

       •   database name (see DBI(3) for details)

       •   database user name

       •   database pass word

       Once this is setup, you can access the names and values for the mysql performance metrics
       by doing the following as root:

               # cd $PCP_PMDAS_DIR/mysql
               # ./Install

       If you want to undo the installation, do the following as root:

               # cd $PCP_PMDAS_DIR/mysql
               # ./Remove

       pmdamysql is launched by pmcd(1) and should never be executed directly.  The Install and
       Remove scripts notify pmcd(1) when the agent is installed or removed.

Binary Status values in text

       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num
       extension and the values of 1 (YES/ON) or 0 (NO/OFF).

   Eg:
       •   mysql.slave_status.slave_io_running

       •   mysql.slave_status.slave_io_running_num
